Analysis of the content of chemistry topics from the book of experimental sciences of the seventh grade of the academic year 1401-1400 according to the method of William Rumi

The purpose of the present research is to investigate the chemistry topics of the new book written by seventh grade experimental sciences in the academic year of 1400-1401 based on William Rumi's method. To what extent are the sentences and pictures of the chemistry topics of the seventh grade experimental science book actively edited? This research was conducted using quantitative content analysis and descriptive statistics. The studied community in this research was the chemistry section of the new book of experimental sciences of the seventh grade of the academic year 1401-1400. The results of the study showed that the conflict index for the sentences of the chemistry texts in the book of experimental sciences of the seventh grade was 0.54 and for the images of these texts, the appropriate range was 1.06. Considering that the correlation coefficients of the chemistry content of this book are close to 0.5 and more distant from 1.5, therefore and on the other hand, to improve the quality of science education, its content should be designed in such a way that students are guided to understand the material, the content of this book is relatively actively composed, but it is far from the ideal situation.
